Patent DE-3211839-A1 (DE)
Title: Device for the volumetric metering and dispensing of quantities of liquid
Inventor: VOEGELE GUENTHER
IPC: G01F15/00
Filed: 1982-03-31
Abstract: A volumetric metering and dispensing device for liquids has a metering chamber (21), an inlet valve (16) and an outlet valve (19), as well as a buoyant valve member (44) which blocks the outlet (26) and the overflow (36) of the metering chamber. In order to prevent the valve member from shutting off the overflow during the treatment of the device with a cleaning agent and/or a sterilising agent, the metering device has a displaceable tappet (46) in the region of the overflow and, in one position, this tappet acts as a stop for the valve member to prevent it from closing. <IMAGE>

Title: Use of derivatives of arylsulphonic acids as viscosity regulators for highly viscous industrial surfactant concentrates
Inventor: LINDE KARLHEINZ
IPC: C09K23/12
Filed: 1982-10-23
Abstract: The viscosity of aqueous highly viscous industrial anionic surfactant concentrates, in particular concentrates containing at least 30 % by weight of  alpha -sulpho-fatty esters, is not more than 10000 mPa.s at 40 DEG C if arylsulphonic acid compounds in amounts of 0.5 to 10 % by weight, based on the surfactant concentrate, are added as viscosity regulators to the concentrates. Suitable viscosity regulators are in particular the sodium salt of N-chloro-p-toluenesulphonamide and the sodium salt of N-chlorobenzenesulphonamide. The addition of these compounds also results in permanent brightening of any dark surfactant concentrates.

Title: Device for electrical length measurement at a plurality of measuring points
Inventor: SCHWAER ERNST
IPC: G01B7/02
Filed: 1983-03-19
Abstract: Device for electrical length measurement at a plurality of measuring points at which mechanoelectrical probes are arranged which are connected to an AC voltage source and output voltages which correspond to the particular scanned lengths and are applied sequentially via switches to an evaluation circuit common to all probes. Instead of the conventionally employed demodulator in the evaluation circuit, which requires a comparatively long measuring time, evaluation of the voltage output by the probe respectively connected is performed at a prescribed phase instant, that is to say during an extremely short time interval, so that the measuring time per probe is substantially shortened and the measurement operation of a large number of measuring points is so short that piece-for-piece monitoring is possible using one device in the production process (drawing). <IMAGE>

Title: Method of producing a subaqueous tunnel
Inventor: WIECHERS HEINRICH DIPL ING
IPC: E02D29/07
Filed: 1983-10-25
Abstract: The invention relates to a method of producing a subaqueous tunnel, preferably of reinforced concrete, in which the tunnel tube is produced section by section in an advancing trench, is closed at the front end by an end bulkhead and is fed along the tunnel gradients by means of feed presses in timed sequence with the production of the sections through a sealing portal of the advancing trench into a feed channel dredged out beforehand and filled with water. In order to avoid expensive underwater work for producing guide and supporting bodies over the entire length of the feed channel, the tunnel tube, designed continuously in one piece in the construction state as flexurally rigid bar, is fed in a freely projecting manner up to the first of several guide yokes as well as between the guide yokes. The guide yokes are arranged at a greater distance apart in accordance with the tunnel gradients along the feed channel for guiding the tunnel tube in the vertical and horizontal direction. The vertical position of the cantilever tip, floating freely under water, of the tunnel tube is measured during the feed and is kept at the respective desired value by ballasting. According to the invention, the guide yokes are equipped with both a cross member, which is provided with supports for the tunnel tube and is mounted on lateral posts in a vertically adjustable manner, as well as with adjustable side guides.

Title: Electrotherapy apparatus
Inventor: KRAUS WERNER DIPL PHYS
IPC: A61N1/40
Filed: 1983-11-11
Abstract: An electrotherapy apparatus is described which contains a radio frequency applicator in combination with a low-frequency applicator. The radio frequency applicator causes a radio frequency vibration to act on a region of tissue to be treated in order to heat it, while the LF applicator causes a very low-frequency vibration at a frequency of, for example, 0.02 to 20 Hz and with a field strength of, for example, 1 to 50 mT to act on the region of tissue to be treated. The low-frequency electromagnetic alternating field amplifies the desired effects of the heating produced by the RF vibrations, while the harmful effects of heating are simultaneously substantially reduced.

Patent DE-3346179-A1 (DE)
Title: Control arrangement
Inventor: RUPPERT MARTIN DR ING
IPC: B21H1/22
Filed: 1983-12-21
Abstract: The invention relates to a control arrangement for positioning a drive as a function of reference variable values variable with time. The type of control involved is preferably that of the roll gap of a profile rolling machine for the production of profiled workpieces. In order to compensate the lag error of the driving cylinder for the roll gap, an additional actuating signal is impressed on the control circuit in an open control loop, this actuating signal being generated as a function of the rate of change of the desired values. This an inverse signal which is combined additively with the output signal of a controller and, in the case of changes in the desired values, delivers a superproportional actuating signal. In this way, the lag error can be reduced to such an extent that very high accuracy is achieved. <IMAGE>
Patent DE-3346184-A1 (DE)
Title: Control block with a plurality of directional control valves
Inventor: DISTLER JOSEF
IPC: F15B13/06
Filed: 1983-12-21
Abstract: The invention relates to a control block with a plurality of directional control valves in a common housing. The directional control valves serve to control the pressure-medium paths between a plurality of hydraulic cylinders and a pressure-medium source or tank. A combined pressure-relief and after-suction valve is provided on the primary side between the high-pressure passage connected to the pressure-medium source and the relief passage connected to the tank. The pressure relief serves to protect the hydraulic cylinders against excessively high pressures; the after-suction function prevents the pressure in the high-pressure passage from collapsing and the high-pressure passage from being sucked empty if a load hanging on a hydraulic cylinder is lowered. This is because the cylinder space increasing during the lowering of the load is refilled with working medium from the tank via the after-suction valve. Since the combined pressure-relief and after-suction valve is arranged on the primary side in the control block, the pressure-relief and after-suction function for all downstream directional control valves of the control valve is effected by a single combined valve. <IMAGE>
